T all whom may concern:

Be it known that T, FRANK P. Hmon- BRANDT, a citizen. of the United States, and a resident of Saugerties, county of Ulster, State of New York, have invented certain new and useful Improvements in Paper- Rolling Machines, of which the following is a specification.

My invention relates to improvements in paper rolling machines, the main object of the invention being to provide a machine of this class which is simple andefficient in operation and construction, and to this end, the invention comprises various combinations of features, as more particularly set out in. the appended claims. The machine may be used for rolling paper napkins, pa per towels, &c., particularly crepe paper. The accompanying sheet of drawings illustrates a machine embodying the improvements in one form.

In the drawings Fig. 1 is an elevation of the machine. Fig. 2 is a plan view of the same, certain parts being broken away to more clearly illustrate others. Fig. 3 is a perspective view of the rotary cutting knife. Fig. 4.- is a detail, illustrating parts which directly roll the paper. Fig. 5 illustrates the roll of paper as it comes from the machine. 6 illustrates the paper roll after it is folded by hand, and Fig. 7 is a section taken on the line 7-7 of Fig. 2.

Referring to the drawings, 1 represents the supply roll of paper which is rolled upwardly and over a cross-bar 2 by means of rollers 3 and 4. The paper is then fed downwardly and upwardly, to form a loop, and then passes over a cross-bar 5. from which it is fed by means of rollers and 16 downwardly over a plate 6 and cutting edge 7. which cutting edge cooperates with the rotary knife 8 to out the strip of paper into suitable lengths. The cut-off piece of paper is then conveyed by substantially horizontal. belts 9 on which it drops until it meets the upright belts 10, which forces the paper upwardly until it meets the obstructing fingers 11, so that the paper is caused to be formed into a roll, as indicated in Figs. 1 and 4. The roll of paper is then taken from the machine by hand and the operator then flattens it down, as shown in Fig. 5, and folds it once or twice and pastes a band around it, sothat the final product takes the form shown in Fig. 6.

Seria1 No. 137,616.

The roller 3 is mounted in the side frames 13 of the machine, while the roller d'simply lies loose on the inclined faces 12. 1 l1*lrepresent pins which guide the paper over the plate 5 to the feeding rollers 15 and 16. The plate 6 is provided with fingers 17, which rest in circular grooves 18 in the roller 16, so that the paper is stripped fromthe roller 16 and caused to be fed downwardly over the plate 6. The cutting edge or member 7 is fastened to a cross-bar 19, which is adjustable by means of adjusting screws 20. The rotary cutting knife 8 is carried by means of a rotary shaft 22, which on one end carries a pulley 21, partly surrounded by belt 23, carrying on one end a weight 24 and the other end of which is fastened to the table 25 which is fastened to the top of the frame of the machine. This belt 23 therefore forms a friction retarding means, which takes up any slack in the mechanism which drives the rotary cutting knife, so that it always cuts the paper into pieces of the same length.

The power for criving the apparatus is derived from the belt 26, which drives the pulley 27 on the shaft 28. Shaft 28 carries a sprocket wheel 29, which transmits power to sprocket wheel 30 by means of a sprocket chain, sprocket wheel. 30 being secured to the shaft 22., which carries the re tary cutting knife 8. Shaft 28 also carries a sprocketwheel 31, which, by means of a sprocket chain, transmits motion to a sprocket wheel 32 on a shaft 33, which. shaftcarries pulleys 34-. and 39. Pulley 3 1 trans-- mits motion to the feed roller 3 by means of a belt passing over a pulley 36 secured to the feed roller 3. The shaft of the feet roller 3 also carries a cone shaped pulley 27, which, by means of a belt drives a cone shaped pulley 38 fixed on the shaft of the feed roller 16. The position. of the belt 50 on the cone pulleys 37 and 38 is adjusted by means of a belt shifter (see 7), adapted to slide la terally on a rod 52 secured tothe frame of the machine. The belt shifter 51 is adjusted laterally by means of the adjusting screw 53, which is provided with a hand wheel 54. By this arrangement the relative speed of the feeding rolls 3, 4:, and feeding rolls 15, 16 is adjusted so as to maintain the loop of paper therebetween of the desired length. When operating on crepe paper, it is found that without stretched or torn. Especially this so with different crepe papers, some of which have more crepe or stretch in them than others.

Pulley 39 onshaft 33 drives a pulley 40 on shaft 4 1, which carries a roller l2, over which pass the belts 9, the other'end of the belts passing around the roller 43. Intermediate the rollers 42, 43', the belts 9 pass between idle rollers 47 and 48, mounted in grooves 49 in the side frame of the machine. The set of belts 10, which are substantially at right angles to belts 9, pass over the roller 43 and also the roller 44, being driven by the roller 43, which is, in turn, driven by the belts 9.

As the paper is fed downwardly over the plate 6, it drops upon the conveyor belts 9, and at the proper time is cut off by the rotary cutting knife 8. The cut-off strip then approaches the belts 10, which cause the same to turn-upwardly, and the roll formation started. The fingers 11 positively di rect the paper backwardly, so as to complete therolling of the paper in a satisfactory manner.

It will be clear that many changes and modifications may be made without departing from the spirit and scope of the invention in its broader aspects, and hence it is desired to cover all arrangements coming within the language of the appended claims.

WVhile certain features of the construction disclosed herein for the purpose of making clear my invention have not been claimed, the right to claim such features, particularly the feeding mechanism, is specifically reserved.
